What Python distribution are you using and on what system? At first glance this might be new behavior of pkg_resources; for me it doesn't raise an exception if the file isn't found.

[fromagek]

I tryed it on two systems. One was Linux mint Quiana, the other Debian testing:

florian@flori-notebook:~$ lsb_release -a
No LSB modules are available.
Distributor ID: Debian
Description:    Debian GNU/Linux testing (jessie)
Release:    testing
Codename:   jessie

florian@flori-notebook:~$ uname -a
Linux flori-notebook 3.14-2-amd64 #1 SMP Debian 3.14.15-2 (2014-08-09) x86_64 GNU/Linux

florian@flori-notebook:~$ python --version
Python 2.7.8

Not shure was Python distribution means. I just installed Python/spyder from the Ubuntu/Debian repos. I think python version was the same on both systems.

I tryed https://stackoverflow.com/questions/7446187/no-module-named-pkg-resources

Setuptools version 0.6c11 or greater has been installed.

but it didn't solve the problem.

[ptomato]

OK, I will try it on Debian and see if I can figure out what is going on.

fromage88,

I don't know python, and I don't know the Beams code, but after having the same problem, I checked for files like "about.png"

Stock distribution:

$ find ./ -name "*png" -exec ls -lat {} \; -rw-rw-r-- 1 dave dave 679 Mar 23 2014 ./beams/icons/stock_about.png -rw-rw-r-- 1 dave dave 701 Mar 23 2014 ./beams/icons/camera-video.png -rw-rw-r-- 1 dave dave 911 Mar 23 2014 ./beams/icons/stock_save.png -rw-rw-r-- 1 dave dave 781 Mar 23 2014 ./beams/icons/gtk-quit.png -rw-rw-r-- 1 dave dave 464 Mar 23 2014 ./beams/icons/stock_properties.png -rw-rw-r-- 1 dave dave 864 Mar 23 2014 ./beams/icons/camera-photo.png

$ grep find_icon MainWindow.py from IconFinder import find_icon image=find_icon('about'), image=find_icon('save'), image=find_icon('quit'), image=find_icon('camera-video'), image=find_icon('camera-photo'),

Since about.png, save.png, and quit.png did not exist in the distribution, I created files with those names by copying the existing files, for example copying stock_about.png to about.png.

That solved the "KeyError" problem.

Hey dtaviation thanks for your hint. That seemed to work for me too. Unfortunately I am stuck with the following error now:

any advice?

Hello,

I've got the same problem, but solution proposed by dtaviation is not working for me.

Please help!

[ptomato]

I'm so sorry for leaving this for so long (see #2). I've fixed the above two errors and will release a new version soon; checkout git master if you want to use it already.

@trygentoo Is it not working for you because you hit the same error as @fromage88 or is something else malfunctioning? When reporting bugs, it helps if you're very specific.

[trygentoo]

I get the same output in terminal as @fromage88 and tried to use solution by @dtaviation, but it doesn't help: get the same output.

Thank you.

[trygentoo]

Hello again,

I've tried to run version from git master, but it results in segmentation fault:

$ beams
/usr/lib64/python2.7/site-packages/traits/trait_handlers.py:1599: FutureWarning: comparison to None will result in an elementwise object comparison in the future.
  if value in self.values:

/usr/lib64/python2.7/site-packages/chaco/array_data_source.py:123: FutureWarning: comparison to None will result in an elementwise object comparison in the future.

Hope you will find some time to check this. Thank you.

See #3; I'm working on it.
